Microorganism: Prokaryote/ Eukaryote/neither: Average size (range & units): Unique characteristics (how is each microbe different from the others): Bacteria Prokaryote Cell wall are composed of peptidoglycan-a polysaccharide. Bacteria move with finger like flagella about 20 nm in diameter, which grow at the tip and rotate counterclockwise in bundles to cause runs and rotate independently clockwise to cause tumbles. Pili in bacteria is used to exchange of DNA. All bacteria have cytoplasmic membrane

very large group of arthropods, usually treated as a subphylum, which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. The 67,000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in), to the Japanese spider crab with a leg span of up to 12.5 ft (3.8 m) and a mass of 44 lb (20 kg). Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects,

discovered. The species was found in Marble Canyon site at the north end of the Kootenay National Park in the Canadian Rockies in Canada, as part of the Canadian Burgess Shale fossil deposit on the Alberta B.C. border. The ancient predator was an arthropod that swam the Cambrian seas. Due to the fossil’s age it was determine that the creature predated the dinosaurs by some 250 million years, living 509 million years ago. Fossil evidence shows the creature was a marine species of about 10 centimeters

People across the globe are struggling with arthropod-borne flavivruses, and the treatment of these viruses has so far been very limited. A compound called arbidol (umifenovir) has been seen to counteract the affects of several viruses. The drug is currently being used in Russia and China for the treatment of prophylaxis and influenza. The way arbidol works is by inhibiting the membrane fusion between the virus particles and the plasma membrane of a cell as well as endosome membranes. This basically

Question 1 Names of aquatic plant | Parts and its fuction | Water hyacinth (Eichhornia Crassipes) | The stems and leaves contain airfilled tissue which give the plant its considerablebuoyancy. | Duckweed (Lemnaceae) | Entire lower surface of fronds can absorb nutrients from the medium, and the plants can grow well under conditions which entirely prevent root elongation. | Water Primrose (Ludwigia) | The creeping and floating stems allow it to find open water and sunlight through the larger

Many other diets and feeding styles have been suggested such as searching for burrowing arthropods or skim-feeding with evidence for them eating arthropods based on the association of trace fossils of invertebrates with the Quetzalcoatlus whereas the gape is compared to other skim-feeders serving as evidence for feeding in that manner (Witton et al, 2008). However, the fossil

the rapid excretion of drugs (Alves et al.2008). Insect succession Insect succession is the wave or pattern of insects’ colonization on dead remains and is also affected by the surrounding environment. Invasion of a body by insects and other arthropods occurs soon after death (Anderson and Goff, 2000). They are capable to arrive and colonized within minutes of the death (Wells and Lamotte 2001). It is not unusual for human remains to be discovered in a highly decomposed or skeletonized state.

Comparing LC50 of Insectisides Pirimicarb and Rotenone on Blowfly, Blowfly larvae, Woodlice and Daphni Abstract The LC50 of insecticides rotenone and pirimicarb were compared by testing blowfly, blowfly larva, woodlice and daphnia. Rotenone is a NADH dehydrogenase inhibitor causing death by oxidative stress however pirimicarb causes toxicity through acetylcholinesterase inhibition. It was found that rotenone had large toxic effects on daphnia, blowflies and woodlice but not maggots and pirimicarb
